Alpha Centauri: November 2017

We use more than a decade of radial velocity measurements for α Cen A, B, and Proxima Centauri from HARPS, CHIRON, and UVES to identify the Msini and orbital periods of planets that could have been detected if they existed.

The deadline is quickly approaching for the BoldlyGo Institute crowdfunding campaign to search for Earth-like planets circling Alpha Centauri. All donations are now being doubled - matched dollar-for-dollar by a generous donor.
